Vertical oil pump provided with viewing window

Abstract

The invention provides a vertical oil pump provided with a viewing window, and belongs to the technical field of oil pumps. The vertical oil pump provided with the viewing window is simple in structure, diversified in transporting types, and low in noise and vibration. The vertical oil pump provided with the viewing window is characterized in that a lower housing is provided with a vertical channel, wherein connecting flanges are mounted at two ends of the lower housing; an upper housing is provided with an inner chamber, and the lower end of the inner chamber of the upper housing communicateswith the middle part of the inner channel of the lower housing; a diversified is in sealing connection with the inner chamber of the upper housing; a cylinder body is in sealing connection with the upper end of the upper housing; a piston rod of the cylinder is in sealing sliding connection with the inner chamber of the upper housing; the viewing window is mounted on the upper housing in a sealing manner; and the viewing window is arranged at the diaphragm. The vertical oil pump provided with the viewing window is simple in structure; the pressure in the lower housing can be adjusted by telescoping the cylinder, and thus the purpose of sucking and draining liquid is achieved; few parts are in contact with liquid; the vertical oil pump can be mounted in various special conditions and is used for pumping mediums which cannot be pumped by general pumps; and moreover, the vertical oil pump is low in noise and vibration.

Description

technical field [0001] The invention belongs to the technical field of oil pumps, in particular to a vertical oil pump with a window. Background technique [0002] The vertical oil pump is a kind of equipment used for lifting and transporting oil. The existing vertical oil pump has the advantages of continuous and uniform flow and less wearing parts, but it has the problem of being sensitive to the viscosity change of the liquid and the existing Most of the vertical oil pumps are driven by a motor and an impeller with an extension shaft, which has defects such as vibration due to poor concentricity of the extension shaft. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a vertical oil pump with a window, which has a simple structure, a variety of transportable types, and less noise and vibration. [0004] The technical solution adopted by the present invention is: a vertical oil pump with a window, ...
